The market for audio applications and devices has significantly grown over the last couple of years. Applications such as smart speakers, Bluetooth speakers, smartphones, and voice-controlled ...

In previous installments of the AudioFile, we've talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We've also discussed the process of ...

Basic review of how the different kinds of analog-to-ditital converters wor, with a sidebar relating them to appropriate applications. ADCs quantize time-varying analog voltages into a sequence of ...

The most important thing to remember about both DACs and ADCs is that either the input or output is digital, and therefore the signal is quantized. That is, an N-bit word represents one of 2N possible ...

In part 1 of this pair of articles, we ran SPICE noise simulations on a simple second order lowpass filter. We saw that there is something fundamental about the ‘hold’ that the filter’s capacitor ...

Cypress's Dave Van Ess proposes a novel way of analyzing mixed-signal circuits in terms of serializing the digitized analog signal and then assesing the relative time the signal is high. As an “old ...

We casually speak of digital audio, often referring to it as AES audio, perhaps AES3 (for the number of the AES standard), or by an older term AES/EBU. But what exactly is this AES3 signal? Here’s the ...
